that I include the intersecting ducts or pas siege-ways for the compressed sir and oil, and thy enlarged chan'ihers or spaces for altering the velocity of the mixture during the atoniizing operation. hi Fig. 3, is the cylindrical valve easing having a nozzle outlet 2l controlled by n noodle valve 22, and the oil inlet 23 and eonnnressed air inlety 24. The stein ol' the needle valve 22 posees rearward ly through a stelling box 25 midis provided ut lis rear end with a hc ad or collar 26 with which engages expansion spring 27, held in plaeehy a suitable stop :is shown at 28. An operating lever 29, journaled at 3() engages the head or coller 2G for opera-ting the' needle` valve against the action. ol the spring 27, wh ich latter normally holds the needle valve closed.

Mounted upon the stein of the needle valve 22, Wit-hin the cylindrical casing 20, is a cylindrical head or iston formed with two or more deep oy indrical grooves or re cesses 35, which divide the piston into s plurality' of piston sections which snugly fit the bore of the valve casing 20. The periphery of cach of the piston4 sec-tions is grooved or channeled with a series of intersecting ducts or passage-Ways 37 and 3S, which coxnmunieste at their ends with the spaces at the ends of the valve casing and with the spaces 36' between the piston sections.

The operation of the atoniizing spray nozwlth but i.,

zle shown in Fig. 3 will be clear few words of explanation. The oil and compressed air supply ports beingr properly mmu nepmv. with the supplies o ml md (-0,11- pressed air, ail-fl 11h? Qui-lfd' Qpening 2i of the nozzle being in proper position in the wall of -the working cylinder of the engine, the

needle valve is opened by the operation of the lever 29, through any suitable automatic mechanism, not shown, with the result that the compressed sir rushing through the nozzlc casing and intersecting ducts or passageways and enlarged spaces, will drew the oil through said intersecting passages and spaces at a great velocity, quickly breaking up the oil into its atoms, and thorou lily n iixing it with the compressed air, disc urging a perfect spray of oil into the cylinder f the engine.

I have shown several forms ofidevices for illustrating the purpose of my invention. I would have it understood that I do not limit n ifself to any of these specific forms, Aont cons1 er my invention to consist broadly oi en the ducts or passage-Ways, ior rapid y and 6o;

effectively atomizing oil through. the use of compressed an: It will, or' course, he understood that the intersecting duets or passages may be arrange-d at any suits-ble or'desired angle, so long as they accomplish the result o 5 pointed out, which is the atomizing of the oil and mixing it with the, compressed air.

Having thus described my invention, 'what I claim as new and desire te secure. hy jjtters Patent is:
